The Staff of Elements was forged from two rare elements: Blue Crystal found in the Crystal Caves, and Chrono-steel. Chrono-steel is the only metal that is capable of absorbing the powers of living beings. Atop the staff is a Blue Crystal orb which is essential to its function, as it makes it possible for the staff to contain the powers of more than one person at once. Together, he who holds the staff holds the power. The energies of the staff would corrupt any who wielded it. Master Chen used the staff to steal the elemental powers of the fallen fighters in his tournament. Cole destroyed the staff, and the powers it contained were returned to the elemental masters.
